Former NFL star Darren Sharper is set to be arraigned Thursday in Los Angeles on rape and drug charges in an investigation into allegations that he drugged and sexually assaulted at least seven women in four states.

Sharper, 38, was charged last week with seven rape and drug counts involving four women he allegedly met at a West Hollywood nightclub. Court documents filed Friday revealed additional allegations in Las Vegas, New Orleans and Tempe, Ariz., that are all still under investigation.

The former New Orleans Saints safety appeared in court for the first time Friday but did not enter a plea as his arraignment was pushed to Thursday afternoon.

He remained free on $200,000 bail posted after his Jan. 17 arrest but was ordered to surrender his passport, stay in L.A. and avoid the West Hollywood club.

If convicted of the charges, Sharper faces more than 30 years in state prison, prosecutors said.

His attorneys said last week that Sharper is innocent.

“We look forward to the true facts being revealed in this case, and we are hopeful that Mr. Sharper will be fully exonerated before this case is concluded,” attorney Blair Berk said outside the courtroom.

The 7 women already named in this case may just be the tip of the iceberg

Los Angeles Police Cmdr. Andrew Smith said the LAPD’s investigation was also ongoing.

“Any time we have a case like this, we are looking for more victims,” Smith said.
